| Abstract: | Mössbauer source and absorber spectra of FeCo2O4 and Fe0.5Co2.5O4 have been obtained between 82 and 523 K. Interpretation of the spectra allow the cation distributions of the compounds to be determined. FeCo2O4 is Co2+0.55Fe3+0.45Co2+0.45Fe3+0.55Co3+1.0]O4 and Fe0.5Co2.5O4 is Co12+Fe3+0.5Co3+1.5]O4. Spinel tetrahedral site quadruple splitting is observed in both compounds. |
